Abstract
An LED lamp includes a heat dissipator, a module substrate fixed to one end of the dissipator and mounted with an LED chip, a cap mounted via an insulator on the other end of the dissipator, a lighting circuit disposed in the dissipator and/or the cap, a glove having an open end attached to the one end of the dissipator so as to cover the module substrate, an intermediate ring including an engaging portion formed on its one end, and an engaged portion formed on the one end of the dissipator so as to be detachably engageable with the engaging portion. The other end of the ring is bonded with the open end of the glove to be fixed to the open end of the glove. The engaging portion fixed to the glove engages the engaged portion so that the glove is detachably attached to the dissipator.
Claims9
An LED lamp comprising:
- a heat dissipator having two ends;
- a module substrate which is fixed to one end of the heat dissipator and mounted with an LED chip;
- a cap mounted via an insulator on the other end of the heat dissipator;
- a lighting circuit which is disposed in the heat dissipator and/or the cap to supply electric power to the LED chip, the lighting circuit being electrically connected to the cap;
- a glove made of a translucent material and having an open end which is attached to said one end of the heat dissipator so as to cover the module substrate;
- an intermediate ring having two ends and including an engaging portion formed on one end thereof;
- and
- an engaged portion which is formed on said one end of the heat dissipator so as to be detachably engageable with the engaging portion, wherein:
- the other end of the intermediate ring is bonded with the open end of the glove thereby to be fixed to the open end of the glove;
- and
- the engaging portion of the intermediate ring fixed to the glove engages the engaged portion of said one end of the heat dissipator so that the glove is detachably attached to the heat dissipator.

- a cap mounted via an insulator on the other end of the heat dissipator;
- a lighting circuit which is disposed in the heat dissipator and/or the cap to supply electric power to the LED chip, the lighting circuit being electrically connected to the cap;
- a glove made of a translucent material and having an open end which is attached to said one end of the heat dissipator so as to cover the module substrate;
- an intermediate ring having two ends and including ring protrusions formed on an outer periphery of one end thereof;
- and
- a coupling ring having two ends releasably connectable to each other and having an inner periphery formed with a ring groove, wherein:
- the heat dissipator has a flange formed on an outer periphery of said one end thereof;
- the other end of the intermediate ring is bonded to the open end of the glove thereby to be fixed to the open end of the glove;
- the flange of the heat dissipator and the ring protrusions of the intermediate ring are overlapped;
- the coupling ring is wound on the overlapped flange and ring protrusions so that the flange and the ring protrusions are engaged in the ring groove;
- and
- the ends of the coupling ring are connected together, whereby the glove is detachably attached to the heat dissipator.
